1 Claim.

This invention relates to adjustable vises, and it relates more particularly to a vise for use in machine tools, particularly grinding machines, whereby articles may be firmly held and portions thereof shaped to proper angles with respect to each other, such as is required, for example, when tool faces are to be ground at proper relative angles.

The principal object of the present invention is to provide an angularly adjustable vise for use iii-grinding machines and the l'ke which is so constructed and arranged that likelihood of interference with the parts of the machine tools in which the vise is used will be minimized and in which the various adjustments may be more quickly and expeditiously made than in the devices of this character at present in use;

A further object of the invention is to provide a novel device of the character aforesaid which, while afiording a high degree of accuracy will, nevertheless, be relatively inexpensive in construction, by reason of the use therein of a vise proper which is readily available, and which may be separately used if desired.

A further object of the invention is to provide a device of the character aforesaid which will permit the adjustment of the same to various positions, and permit the use of the same in such adjusted positions, without interference by or with the parts of the machine tools in connection with which the device is used.

The nature and characteristic features of the invention will be more readily understood from the following description, taken in connection with the accompanying drawings forming part hereof, in which:

Figure 1 is a side elevation of an adjustable vise embodying the main features of the present invention;

Fig. 2 is a top or plan view thereof; and

Fig. 3 is an end elevation thereof.

It should, of course, be understood that the description and drawings herein are illustrative merely, and that various modifications and changes may be made in the structure disclosed without departing from the spirit of the inven tion.

Referring to the drawings, in the particular embodiment of the invention therein shown, the vise proper comprises a frame member made of two longitudinal bar-like extensions l having an integral upwardly projecting jaw l I at one end, and at the other end an integral lug l2 in which a. tightening screw I3 is threaded. The outer end of the tightening screw I3 is provided with a hand lever l4 of the usual type, comprising a rod which passes through a head portion ii of the screw l3 and is provided with an enlargement I6 at each end so that said hand lever I4 may be moved to the most advantageous position for turning the screw I3.

The inner end of the screw I3 is journaled in a movable jaw member I! which has a portion 18 extending downwardly into the space between the two bar-like extensions ID of the frame of the vise proper. The lower portion of each of the members It! is recessed whereby a retaining block l9, carried at the lower end of the extension l8 of the movable jaw member l1, will serve to prevent the movable jaw member l-l from being displaced from the frame members It]. a

The foregoing type of vise proper is of a well known construction and commonly used in connection with various machine tools, such as drill presses, shapers, .milling machines and th like.

The jaw portion H of the vise proper is. however, secured to a disc member 20 by means of bolts 2|, and the disc member 20 is secured to a plate member 22 by means of a bolt '23, which extends therethrough-and serves not only as a fastening means but also as a pivot about which the disc member 20 and the parts carried thereby may be rotated on the axis provided by the bolt 23.

The bolt 23 is provided with a nut 24 threaded thereon and positioned in a recess 25 in the rear of the plate member 22, the arrangement being such that when the nut is tightened on the bolt 23 the vise proper will be held in a fixed position on the axis provided by the bolt 23.

The peripheral surface of the disc member 20 is provided with suitable graduations indicating angularity and the plate member 22 is also provided with a line indicator so that the position of the vise proper about the axis provided in the bolt 23 will be indicated to the user.

The plate member 22 is pivotally supported by means of a pin 26 mounted in segment lugs 21 which extend upwardly from a horizontal plate member 28. The axis of the pivot pin 26 is transverse to that of the bolt 23 which is provided for the initial angular adjustment of the vise proper.

Sector shaped links 29 are provided on each side of the device. The links 29 are secured respectively to the plate member 22 and to the horizontal plate member 28 by means of bolts 30 passing through the slots 3| of said sector links 29.

At least one of the segment lugs 21 to which the plate member 22 is pivoted by means of the pivot pin 26 is provided on its outer surface with suitable graduations for indicating the angularity of the plate member 22 with respect to the horizontal plate member 28. This adjustment is accomplished by loosening the bolts 30 and thereafter tightening the same when the plate member 22, and the vise proper carried thereby, have been brought to the desired angular position about the. axis. provided by the pin 26. Itshould here be n'otedfthatthe axis of the pivot pin 26 is so located that the plate member 22 may, if desired, be brought to an extreme horizontal position.

The horizontal plate member 28 is"s'ecured to or integral with a disc member 32 having angular graduations on its peripheral "surfa'c'e.""'Said horizontal plate member 28 andidis'cmemberi32 are pivotally mounted on a base member 33 having slotted lugs 34 for securing the deviceon the work table of a machine tool such as a grinding mac-tangerine like; The" means-for securin plate member 2 B and disc member to "theba'se plate 33 com rises a bol t member 35 having "a slottednut SBthreaded thereon, the arrangement being such thatafter the adjustment of plate member 28 and the parts carried thereby "has been 'made aboutfthe vertical axis provided by the bolt T member {35, the nut/ 36' is tightened to secure the partsin the adjusted position. The periphery of the disc member 32"is 'graduated 'to indicate the 'fangularit'y' so that the-proper posi tioning 'of the'parts about the vertical axis may be kfiOWhJ e 7 It will be noted that, by the foregoing arrangenient', ther'eisprovided a vise which maybe readily adjusted "to various "angular "positions about three component axes. The adjustment in each instancemay be made easilyhnd expeditio'usly, and the"variousparts or'uie structure are'so "constructed and arranged as to minim'i'ze th'e*'likelih'odd' of "any "interference between the various parts of the device and thefpartsofthe tools for operating" upon the work which maybe mounted inthe vise proper, I r

ltjwillal's'o' be notedthat 'the pivotal axis'of the' dis'c member 'is parallel to the clamping axis of the vise; that is, tothe direction of travel of the movablejaw'of said vise. 'By thisarrang- 4 ment, the various operations of the machine tools in connection with which the vise is used will be greatly facilitated, and the work may be set up in much less time and with less likelihood of error.

I claim:

An adjustable vise comprising a vise proper consisting of a frame work carrying a fixed jaw,

a. movable jaw mounted onsaid frame work, and imeans forradvancing and retracting said movable jaw with respect to the fixed jaw; a

the vise proper is secured, a plate member on "whichsaid disc member is pivotally mounted,

the pivotalaxisof said disc member being parallel'to thedirection of travel of the movable jaw b'er; "means for supporting said plate member comprising a horizontal plate member havingupwardly 'pro jecting lugs, a "pivot connecting-f said lugs and saidf-plate 'me'mberfi means for securing said-plate member inadjusted -positions with'respect to the horizontal plate member comprising slotted-sector 'links and 'bol'ts for securing -said linlgs to said plate members; a{ base plate-upon whichsaid' members are mounted, and means "for pivoting said horizontal plate member abouta verticalaxis "and v securing the isafne in adjusted angular'positionson the base pla'te.
